Laser cleaning has solved many unsolvable problems. The manufacturer of laser cleaning fume purifiers, Pure-Air, will analyze the little knowledge in laser cleaning for you.

One is to use the cleaning substrate (also called the matrix) and the surface attachment (dirt) to have a great difference in the absorption coefficient of a certain wavelength of laser energy. Most of the laser energy radiated to the surface is absorbed by the surface attachments, so that it is heated or vaporized and evaporated, or instantly expanded, and is driven by the formed airflow to separate from the surface of the object to achieve the purpose of cleaning. The substrate will not be damaged due to the very small absorption energy of the laser of this wavelength. For this kind of laser cleaning, choosing the right wavelength and controlling the laser energy is the key to achieving safe and efficient cleaning.

Another type of cleaning method is suitable for cleaning the laser energy absorption coefficient between the substrate and the surface attachment, or the substrate is more sensitive to the acid vapor formed by the heating of the coating, or the coating will generate toxic substances after the heating. This type of method usually uses high-power and high-repetition rate pulsed lasers to impact the cleaned surface to convert part of the beam into sound waves. After the sound wave hits the hard surface of the lower layer, the returned part interferes with the incident sound wave generated by the laser, generating high-energy waves, causing the coating to explode in a small area. The coating is pressed into powder and then removed by the vacuum pump. It won't hurt.

It can be seen that this type of cleaning has good decontamination ability for its own subdivisions. Pure-Air laser cleaning dust purifier manufacturers have been manufacturing laser cleaning smoke filters with a professional attitude for many years.
